Hello,
I'm currently seeing a hang while booting Linux (5.10.72-2.2.0) when I try to enable the GPU on a custom i.MX 8M Nano board (based very closely on the Nano DDR4 EVK)...
The kernel log is attached...
Also here is the gpu entry in my device tree (my .dts file references the imx8mn.dtsi file):
&gpu {
assigned-clocks = <&clk IMX8MN_CLK_GPU_CORE_SRC>,
<&clk IMX8MN_CLK_GPU_SHADER_SRC>,
<&clk IMX8MN_CLK_GPU_AXI>,
<&clk IMX8MN_CLK_GPU_AHB>,
<&clk IMX8MN_GPU_PLL>,
<&clk IMX8MN_CLK_GPU_CORE_DIV>,
<&clk IMX8MN_CLK_GPU_SHADER_DIV>;
assigned-clock-parents = <&clk IMX8MN_GPU_PLL_OUT>,
<&clk IMX8MN_GPU_PLL_OUT>,
<&clk IMX8MN_SYS_PLL1_800M>,
<&clk IMX8MN_SYS_PLL1_800M>;
assigned-clock-rates = <0>, <0>, <800000000>, <400000000>, <1200000000>,
<400000000>, <400000000>;
status= "okay";
};
Disabling this (by setting status="disabled" allows the kernel to boot successfully.
Any ideas on things I could try to get the GPU working? Thanks in advance!
